A number 351 is divided into two parts in the ratio 2:7. The product of the
numbers is-​

Answer 1

Step-by-step explanation:

let the the parts be 2x and 7x respectively

ATQ:

2x + 7x = 351

9x = 351

x = 351/9

x = 39

the two parts are:

2x = 2 × 39 = 78

7x = 7 × 39 = 273

therefore product of the numbers

= 78 × 273 = 21294

Answer 2

Answer:

Step-by-step explanation:

Let common ratio be x

therefore, two part = 2x and 7x

ATQ - 2x + 7x = 351

9x = 351

x = 351/9 = 39

numbers - 2x = 2*39 = 78

               - 7x = 7*39 = 273

Product = 78 * 273 = 21,294
